PiP funtion

I have read the sticky and I think I have a pretty good grasp on it, what I did not find an exact answer on is this scenario -

Running 2 machines with 2 diff wow's on each. SO 1 monitor has wow seperated down the middle on a 17" monitor, and the other (24") has 2 wow's running in full window mode (so i have to swap when main dies).

Can i set up PiP to swap from one machine (with the 17") to the bigger monitor?

I know I need to get another monitor, price pinching with some crap happening @ work lately :-(

OR can I set it up that 3 run on the 17" monitor and have a PiP to bring whoever I need to the big one so that I can see things clearly? Hope this explains it a bit better.

from one machine to another? no

from one monitor to another on the same machine? yes
